Hi boys, I am using a developing M8051EW-based mcu, and I try to support the AGDI interface of Keil. From a few weeks ago, I ran into a corner to discover how to use keil's call stack. The stage i reach now is that stacktree recording needs to be started by activating call stack window. You know, keil simulator can record the stacktree at the very beginning of program started. Anyway, after callstack window is activated, call stack does contain full routes program passed. My question is, what should be initialised for my agdi driver? Or how to call back refreshing the callstack window at the background? thanks, Karah
